The microwave splatter guard works great for bowls and cups. I mainly use it own bowls, both large and small. It doesn't work well on normal plates because the cover doesn't shit high enough over the food to keep from making a mess.

The steam release holes work well to keep too much moisture from going back onto your food. It helps release some of the heat. It can get hot if in the microwave for long periods of time.

I have noticed that the cover will bend or warp when it gets hot. It curves inwards into the bowl. After being washed and cooled off, the cover does regain most of it's original shape.

I still prefer using glass lids or plastic lids to cover my food in the microwave, mostly because they cover the plates. When it comes to bowls or cups, I prefer using the microwave splatter guard because it covers the top completely and keeps the food inside from making a mess.
